摘　　要：本文应用新研制的全气缸取样系统测量了一台S195型涡流室式柴油机气缸内NO_x、CO浓度随曲轴转角的变化历程。考查了负荷、转速和喷油提前角对NO_x、CO浓度变化历程的影响。实验结果同计算机模拟结果作了对比,两者基本吻合。NO_X and CO concentrations during combustion process in the cylinder of an S195 IDI diesel engine were measured by use of a newly developed total cylinder sampling system. The effects of engine load, speed and fuel injection timing on the NO_x and CO formation were discussed. The in-cylinder NO_x and CO formation were also computer-modeled, the results were compared with those of measurements, and a good agreement was achieved.
